METALLIC BARREL.

SPECIFICATION forming part of Letters Patent No. 409,601, dated August 20, 1889.

Application filed January 24, 1889. Serial No. 297,489. (No model.)

To 0055 whom it may concern:

Be it known that I, CORNELIUS J. CURTIN, a resident of High Falls, in the county of U1- ster and State of New York, have invented certain new and useful Improvements in Metallic Barrels; and I do hereby declare the follow ing to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to an improvementin metallic barrels; and it consists in the peculiar construction and arrangement of parts, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

The object of my invention is to provide a metallic barrel which shall be extremely strong and light and adapted to be manufactured at a slight cost.

In the accompanying drawings, Figure l is an elevation, partly in section, of a metallic barrel embodying my improvements. Fig. 2 is a partial end view of the same. Figs. 3 and 4: are detailed sectional views illustrating the manner of securing the heads in the barrel.

7 The sides of the barrel are formed of a single piece of sheet metal A, preferablysteel, rolled from an ingot, and having its edges B overlapped and secured together by rivets C. The barrel is of the usual form, swelled or bulged outward in the middle, thereby adapting the same to withstand a maximum degree of pressure from Without and within. The heads D E are each made of a single piece of circular sheet metal, (preferably steel,) having the outwardly-turned flanges F, which rest within the ends of the barrel.

Rivets G are inserted from within through aligned openings in the flange of headD and in the lower end of the barrel, and the outer ends of the stems of the said rivets are swaged to form heads G, thereby permanently securing the lower head D in place. The

rivets H, which secure the upper head E in place, are inserted from without through aligned openings in the top of the barrel and in the flange of the head, and said rivets have the inner ends of their stems split to form ears I, which, on being opened, as shown in Fig. 3, and clinched on the inner side of the flange of the head, secure the latter very firmly in place.

By pinching or closing the ears I together, the rivets I-I may be taken out and the head E removed from the barrel, as will be readily understood.

It will be observed, by reference to Figs. 1, 3, and 4, that the flanges F of the heads are flared outward, that the diameters of the heads are somewhat less than the interior diameters of the ends of the barrel, and that the greatest diameter of the flared flanges of the heads is equal to the said interior diameter of the ends of the barrel. These flared flanges enable the heads to be readily placed into and taken from the ends of the barrel, and adapt the said heads to be tightly compressed when fitted or driven in the ends of the barrel to effect perfectly-tight joints and prevent leakage. Moreover, the weight or pressure of the contents of the barrel will tend to bulge the center of the heads outward to an approximate concavo-convex form, and thereby expand the flared flanges of the heads and fit the same all the more tightly in the ends of the barrel, thus rendering the joints more secure in proportion to the pressure on the heads.

A barrel thus constructed ,is extremely strong and durable, is light, and can be manufactured and sold at a cost only slightly in advance of that of the ordinary wooden barrels of commerce.

Having thus described my invention, I claim 1. As a new article of manufacture, the metallic barrel having its side formed of a single sheet of metal with its edges overlapped and riveted together, the metallic heads having the outturned flanges riveted within the ends of the barrel, the rivets employed to secure one of said heads being split and provided with ears adapted to be spread apart or closed together, whereby said head is rendered detachable from the barrel, substantially as described.

2. As a new article of manufacture, the metallic barrel having the heads provided With the ontturned outwardly-flared flanges In testimony whereof I have signed this F, fitting in the ends of the barrel and secured specification in the presence of two subscribthereto, whereby internal pressure, by forcing ing Witnesses.

out the centers of the heads, will expand the CORNELIUS J. OURTIN. flanges and compress the same more tightly Witnesses:
